Long Induced Paths in K s , s ${K}_{s,s}$‐Free Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT More than 40 years ago, Galvin, Rival, and Sands showed that every K s , s ${K}_{s,s}$‐free graph containing an n $n$‐vertex path must contain an induced path of length f ( n ) $f(n)$, where f ( n ) → ∞ $f(n)\to \infty $ as n → ∞ $n\to \infty $. Recently, it was shown by Duron, Esperet, and Raymond that one can take f ( n ) = ( log log n ) 1 /
